An online game that tests preschool children’s hearing, a new wifi network that lets parents limit kids’ screen time and an online pet-sitting service are some of the innovative startups that call Sydney home.

To nurture talented entrepreneurs like these, the City has produced a Tech Startups Action Plan, packed with ideas for encouraging the sector – from creating an entrepreneurship centre, to offering ‘how to code’ classes in local libraries and cutting through planning red tape to encourage more co-working spaces.

The plan is on public exhibition until 10 November so the City is calling on the industry to comment before the deadline.

Lord Mayor Clover Moore said Sydney was home to the nation’s highest concentration of tech startups, with a growing reputation for innovation.

“Whether it’s a tablet based game that tests the hearing of preschool children or an online pet-sitting service, these six startups have the potential to reach large global audiences,” the Lord Mayor said.

“The next billion dollar company to follow in the footsteps of success stories like Canva or Atlassian is already being developed, we want to make sure those companies see the benefits of setting up and staying here in Sydney.”

“I’m proud the City is involved in so many initiatives to help these entrepreneurs create innovative products that will make a positive difference in people’s lives.”

Carolyn Mee is the founder of Sound Scouts, a tablet-based game that tests the hearing of preschool children in collaboration with the National Acoustic Laboratories.

Former TV presenter Ms Mee is a graduate of Springboard AUS, an international incubator, a program that helps grow female-led startups sponsored by the City.

“Sound Scouts has already identified a number of children with hearing loss,” Ms Mee said.

“After receiving treatment as a result of the program, one little girl asked her mum why the vacuum was now so noisy. She was hearing properly for the first time!”

Central Sydney currently has the largest concentration of tech startups in Australia. The startup economy2013 reportby PricewaterhouseCoopers found the Australian tech startup sector could generate more than 500,000 jobs by 2033.
